Color Screen
Use the Color screen to enter information about each of
the colors available on the system. The Color screen is
also used to setup system purge time, using Color 0
(page 32).
Color
Select the number for the color you want to setup or edit.
• Only the number of colors selected in Advanced
Screen 2 (page 36) are shown on the Color
drop-down list.
• Selecting a different color in the Setup mode does
not affect the color currently selected on the Opera-
tor Station.
Colors 1-6 Setup
There are five values to set. Use information from the
material data sheet or from your material supplier.
Ratio
Set the volumetric ratio of component A to B from 0.0:1
to 30:1, in increments of 0.1.
Tolerance
Set the ratio tolerance of the color from 1–99% in incre-
ments of 1%. To minimize nuisance alarms, select the
largest tolerance value that meets the paint manufac-
turer’s recommendations and your production require-
ments.
Potlife Time
Set the potlife time from 1–999 minutes in increments of
1 minute. Select a time that is within your material’s
sprayable potlife time so if the potlife is exceeded and an
alarm occurs, you have sufficient time to spray or purge
the mix material from the system.
Purge Time
This setting is used during Purge mode and color
change. It can be set from 0–999 seconds in increments
of 1 second. See ProMix™ II Purge Sequence and
ProMix™ II Color Change Sequence, page 33.
Fill Time
This setting is used during color change to set the
amount of time the system spends loading the new
color. It can be set from 0–999 seconds in increments of
1 second. Set Fill Time for at least 5 seconds longer
than the time it takes to see a new color at the gun. See
ProMix™ II Color Change Sequence, page 33.
Color 0 Setup
Color 0 is used in multiple color systems to purge out
material lines without loading a new color. It is typically
selected at the end of a shift to prevent hardening of cat-
alyzed material.
When you select 0 from the setup Color list, the Color 0
Setup screen appears. Set purge time from 0–999 sec-
onds in increments of 1 second.
